ATENT OFFIC WAGON-LOADING MACHINE.

' Application filedn s,

T0 all whom-it may concern H Be it known that I, CARL J. NORDLUM, acitizen of the United States, residing at Minneapolis, in' thecounty ofHennepin and State of Minnesota, have invente'da new and usefulWVagon-Loadmg Machine, of WlllCll the following is a specification.

Th1sinvent1on relates to wagon loading machines, and theob ect 1s toprovlde an 1mproved, cheap and convenientmachine for Y as to avoid theold time-wasting process of changing horses from the position in whichthey draw the machine and hitching them to.

-a horse-power devicefor elevating and'loadingthe hay, and then.transferring them back .again to the first position every time W j V assoon-as the hay has slid off from the the machine is to. be movedforward.

In the accompanying drawing: r Fig. 1 is a top planlview of the improvedmachine with a'fragment of a hay rack or wagonattached toit. Fig. 2 is aside elevation of" Fig. 1 with a few parts omitted. Fig. 3 is afragmentaryfront elevation of the adjacent corner "of Fig. 2 with therake omitted. Fig. 4 is .a side elevation showing 'morefully the part ofthe machine above line 44 in Fig. 2.

Referring to the drawing by reference numerals, 5 designates the main,frame of the machine,it is flat and partly skeletoned, with a platform6,-which. may be of any desired size. The rear corners of the frame havelaterally extending arms 7, with metal brackets 8, to which supportingwheels 9 are journaled. The front corners have similar arms 10 withbrackets 11, in each of which is journaled the vertical stem 12 of afork 13, having a rocker arm 14 connected by a link 15 to one end of atransverse rod 16, which is slidable in guides 17 on the main frame, andhas its middle portion connected by a link 18 to a crank or rocker arm19 fixed on a steering shaft 20; which shaft may have a universal joint21 (see Fig. 2) and is provided with a steering hand-wheel 22. Saidshaft is journaled in suitable bearings 23, 24, fixed on the frame, andthe forks 13 are provided with supporting wheels 9;

Attached to the rear frame arms 7 are single-trees -25 to which may behitched two specification of Letters Patent. Patented M31214, 1'922.'

horses, one at each side of the machine.

Each horse to have a leader line, 26 'connect-- ing its bit to afastening means 27 on the a front 10 11,- and a hold-back strap .28extending alsov to said fastening means.

The fork shaped rake by which the hay is picked up and loaded into thewagoncon sists of a series of tines 29, guard bars 30* and transversebars 31 and 32. Between the latter two bars are secured the frontendsoftwo long bars 33, whoserear. ends are;

pivoted at 34 to brackets 35 fixed on the f frame, Each bar 33 isconnected to themain I frame, by a foldable brace composed oftwo partlyoverlapped sections, 36, 37, The

overlapping end of each brace section 36 is provided with a"longitudinal slot 38, in which the pivot. 39 of the joint ismovablebutis fixed in the'section 37, and is by a pull;

ing :coil spring 40 connected to the section 36-. The service of saidspring is toswing the rake arms 33 forward of a vertical' position guardbars 30 into the wagon, which action takes place when the rake is in-theinclinedv position shown in Fig.4 and in dotted lines .in Fig; 2 andthus enable the rake to be lowered by its .weight under control of abrake.

or the reversed hoisting means, which will now be described, I J

In the front part of the frame, forward of a seat 41, is mounted anexplosive engine:

42, whose shaft carries a bevel pinion 43 (see Fig. 1) which may beengaged byjeither.

one of two beveligears 44, each of which is fixed on arope drum 45,secured ona slidable shaft .46, or theymay be secured together and beslidable on the shaft. In either case a single shifter lever 47, engagedbetween collars 48 and having its han- 'dle' end engageable with anotched segment 49, will hold the gears either idle or one of themengaged with the pinion so as to'rotate. the two drums in one directionfor hoisting and in an other direction for lowering'the rake, as willappear from the'fact that on each drum or drum section 45 is fixed andpartly wound one end of a cable 50,

which is guided overia sheave 51 and has its 31 by a cable 56. All thebooms are pivoted with their lower ends to the main frame as at 56", orto brackets 56 on same, so as to swing back and forth and the twobars54; are connected at the top by a cross brace 57.

A brake band 58 on one of the rope drums- 45 serves to control bothdrums. Said band is connected by a rod 59 to a brake lever 60,- which isnormally held idle in a notch 61 of a bracket 62.

To describe more exactly the preferable structure of the rake or fork,the tines have their rear ends secured to the lower part of the rakehead by screws or similar means 63; and-forward thereof the tines aresecured together by a cross bar 64:, which bar is preferablyofflat bariron and drawn tight up under the tines b nuts 65, threaded upon thelower ends 66 0-: cheek pieces 67 secured by rivets 68 to the sides ofthe adjacent ends I of the guard bars 80. The latter bars are alsofirmly secured to the bar 32 of the rake head by either screws or bolts69.

70 designatesthe pole or tongue of a hay rake or other wagon? 1. It ispivotally-and detachablyconnected or hitched at 72 to the cross bar 73of the main frame.

In the operation of" the machine, when grain shocks; hay cocks or hay inwindrows vided; the wagon is then attac-hed'with its pole so it will bedrawn close behind the machine. The horses now' draw the machineand thewagon forward with the rake lowered until it has gathered its load; thehorses may then rest, or proceed toward another hay cook or grain shockwhile the engineLQ raises the loaded rake until it tilts backward farenough to discharge its burden into the wagon. The springs 40 now throwsthe'rake forward again past a vertical position and it falls to theground at such speed as the oper ator allows either by the brake 58 andlever 60, or by'throwing the'other gear 44 into mesh with the pinion 43,and letting the engine lower the rake with or without the assistance ofthe-brake,

When the wagon is loaded the horses are hitched to it and haul it to theplace where pivoted with theirrear ends upon the rear end ofthe frame;power operated winding drums 'mounted'on the frame, means for re versingthe drums and operative'connection between the drums and the rake'forraising it from the ground and swinging it upward and" rearward untilits inclined position" causes the dischargingpf its contents rear wardof the machine; said operative connectlon comprising a pair ofupstanding parallelf spaced inner-booms having their upperends'connected together by a transversehori zonta'l brace and their"lowe'i ends pivoted to thefr'ame so as to make thebooms' swing:

ableback and forth in longitudinal direction of the frame a pair ofouter booms like wisepivoted with the lower ends to-the" frame somedistance forward of-thein'nerf booms and crossing thelatterwhen'theTakef is near the ground, cables connectingthe rake with the-tops ofthe innerboonis, cables connecting the tops of the inner booms with thetops of theouter booms,:cables extending from the tops of the outerbooms wthe drums, and guiding means upon the rear "end 5 of the frameforthe lastnientioned cables.
